obsolete fu'ivla x1 is a tuatara [reptile genus Sphenodon] of species/variety x2. For disambiguation purposes, strictly, this word should only apply to members of genus Sphenodon; however, all extant members of reptile order Rhynchocephalia belong to this genus and some semantic broadening is probable. See also: respa, reskuamata.

fu'ivla x1 is a mosasaur [member of family Mosasauridae] of subtaxon/type/genus/species/variety/breed x2. Categorizer rafsi "dis" is meant (and experimentally proposed) to belong to the experimental gismu dinso; as such, it may not be the most elucidating; however, it is technically not essential to the interpretation of the lexeme. Technically, a extinct family of reptile order Squamata (which is extant), but dinso applies all the same (unlike reksa). See also: dinso, respa, reskuamata, ikfio, plesio, dinsauru, reksa, ketslau.
